1990 Galant Overheating

Hi, my friend has a 1990 Galant it has overheatnig problems and we replaced the head gasket, thermostat (190 degrees), and added new Spark Plugs, Wires, and Cap and Rotor. well ontop of the overheating problems he also burning a lot of oil....we changed the head gasket 2-3 months ago but i cant see if there's oil leaking from the gasket...any help would be greatly appreciated, thank you, pat!

Had similar problems with my 90 Galant, checked everything, gasket n all. But when I changed my radiator to a double cell, it solved the problem. I suggest you do the same.
